Another object of the invention is the provision of novel and improved means for forminghollow metallic canes from a blank sheet of metal i'n -an all other respects highly-desirable for thepur means for accomplishing said steps hereinafter more fully described, illustrated in the accompanying drawing and particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the method may be made without departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawing forming a part of this specification', I have indicated the various steps of the method and also a form of apparatus for carrying out the same in which:

Figure 1 is a plan view of a sheet of metal upon which has been provided desired ornamentation, said sheet also showing the relation in which the same'maybe cut to provide hollow'canes in an eflicient and economical manner without lossof material;

' Before the cutting operation is performed;-:-each .of. the individual .bIankS B is. .providediluponeits t surface byganyasuitable method, such',\-ior .-.ex- $30 ample, as by etching or the like with the desired ornamentation, said ornamentation being designated by the letters C and D. To produce this ornamentation on the sheet while in'flat form is a comparatively simple matter and may be done with a minimum of labor and expense. However, to produce the same ornamentation'on a cane already formed would be an expensive operation requiring a great deal of time and skilled labor. It is byreason of the improved method to 40 be hereinafter more fully described that it is possible to produce a cane. substantially the entire surface of Whichmay be suitably ornamented to present various ornamental effects, all this being accomplished ata minimum of cost.

The blank B, which is cut from the sheet A, may be passed through a series of shaping rolls I0, II and I2, so that the blank in passing through the entire series of rolls is transformed from a flat strip into an open tapered tube or cylinder. Thus the first set of rolls will impart to the strip B the cross sectional shape shown in Fig. 3; the rolls II-will impart to said strip the cross sectional shape shown in Fig. l, and the u last set of rolls I2 will complete the formation of the cylinder or tube, bringing the opposite sides thereof into abutting position as shown at in Fig. 5.

It is to be understood that the means or mechanism illustrated in Fig. 2, is merely one of several means that may be employed for performing the operations of transforming the blank B from a fiat strip into an open tube or cylinder. Thus the shapes imparted to the strip, illustrated in Figs. 3, 4 and 5,. may be accomplished by individual dies, the first of which will impart to the strip the cross sectional shape illustrated in Fig. 3, the second of which will impart to the strip the cross sectional shape shown in Fig. 4, and. the last of which may bring about the complete closing of the tube as shown in Fig. 5. In the last two steps it may be necessary to insert a mandrel or rod within the partly formed member, shown in Fig. 4, and the side edges of the strip brought into abutting position enclosed tion of the handle is illustrated in Fig. 6, in which around said mandrel or rod.

After the hollow cylinder has been formed, the larger'end thereof may be bentto form the handle 'l 3. 'One means for bringing about the formaembodiment there is provided a central roller l4 surrounded by a plurality of driven rollers 15.

- By imparting rotary movement to the outer rollmeans of the caps l1 and 18, which caps may be ers 15, the free end of the hollow cylinder or tube may be fed to these rollers to bring about the desired bending of the end of said tube to form the handle l3. A member I6 is provided for holding the body of the tube against movement.

After the last operation has been completed, theopen ends of the hollow tube may be closed by {of any suitable material, such, for example, as brass or the like, and which will add to the attractive appearance of the finished article. If desired, suitable ring members i9 and 20 may be arranged along the body of the cane to still further ornament the same, and at the same time tend to reinforce the same be'light in weight, durable, and will have sub- The finished article illustrated Fig. 7 will stantially the entire surface thereof provided with i highly attractive ornamentation, which ornamentation could not be economically or practically produced on a cane with themethods heretofore practiced for the production of articles of this character.

It is believed that my invention and many of its advantages should be readily understood from the foregoing 'with further description, and should also be manifest that while embodiments of the invention have been shownand described for illustrative purposes, various changes in the shape, size and arrangement of parts may be made without departing from the spirit of the invention or the scope-as defined in the appended claims.

What I claim and desire to secure by Letters Patent of the United States is: 1. The method of forming ornamented tapered hollow canes which comprises providing repeated desired ornamentation on skelp of rectangular formation, subdividing the skelp into blanks which are adjacently inverted end to end in the blank by relatively severing them along cutting lines which are biased in an adjacently inclined relation along the length of the skelp, the degree of bias corresponding to the degree of taper desired in the finished cane, subjecting the ornamented blank so made to a series 'of die pressing operations to form a tubular structure with the edges of the blank in substantial abutment,and then subjecting the larger end of said tubular structure to a bending operation to form a handle. 1

2; The method of forming ornamentedtapered hollow canes which comprises providing repeated desired ornamentation on skelp of rectangular formation, subdividing the skelp into blanks which are adjacently inverted end to end in the K then subjecting the larger end of said tubular structure to a bending operation to form a handle, and then providing closing means in the form oi caps for the open ends of the tubular structure for facilitating in retaining the structure in tubular form.
